Problems solved by technology

However, this verification technology does not improve the verification efficiency of the external functional attributes of the test module. It is only suitable for verifying the internal functions of the test module, and this verification technology is based on clock-driven, so it is not suitable for clock-independent design modules. Functional Verification

Embodiment Construction

[0020] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] figure 1 It is the OVM tree structure diagram in the verification system in the present invention, as shown in the figure:

[0022] The frequency offset module verification system with the OVM tree structure has a clear affiliation relationship, which is very important for the management of transaction data transfer in the verification system, and can reasonably arrange the OVC components as nodes in the tree structure. data transfer. The nodes here are divided into two types, parent node and child node. In the parent node, one or more OVC components represented by child nodes can be declared and used as internal variables, so that the OVC components can be realized through the method of layer-by-layer progression. The coordinated work among them enables the entire verification system to operate reasonably and effectively. The spe...

Abstract

The invention relates to a satellite communication frequency deviation verification method, and belongs to the technical field of application specific integrated circuit verification. According to the method, the OVM open verification methodology relatively popular in current integrated circuit verification is adopted to act as the basic framework of a verification system by aiming at a frequency deviation module in a satellite communication baseband chip, and a transaction-based verification technology, a coverage-driven verification technology and an assertion-based verification technology are integrated together with joint simulation of a C-algorithm model so that automatic contrast and continuous simulation are realized, verification efficiency is enhanced and the verification period is shortened. According to the method, the functional verification of the frequency deviation module of the satellite communication baseband chip is realized, verification efficiency of the frequency deviation module is enhanced, and the method has a nonnegligible effect in successful one-time chip flow of the satellite communication baseband chip.

Description

technical field [0001] The invention belongs to the technical field of application-specific integrated circuit verification, and relates to a satellite communication frequency offset verification method. Background technique [0002] In the ASIC chip development process, the time required for functional verification often accounts for more than 70% of the entire chip development time. The higher the abstraction level of the design, the simpler the design, but there may be more design loopholes at the same time. If If it is an architectural defect, the damage to the chip is even more immeasurable. Therefore, the functional simulation verification before tape-out is the top priority for the entire verification process. [0003] Currently, there are mainly three types of simulation-based functional verification technologies: transaction-based verification technology, coverage-driven verification technology, and assertion-based verification technology. Transaction-based technol...
